The Feeding habits of larval Liparis tanakae collected from the Nakdong River estuary were studied. L. tanakae [3.8-10.6 mm notochord length(NL)] was a carnivore thatconsumed mainly copepods. Its diet also included small numbers of free-living flatworms (Macrostomida), tintinnids, cladocerans, and polychaetes larvae. To evaluate ontogenetic changes in dietary composition, three size groups were designated: 3-5, 5-7, and >7 mm. Copepods were the most important prey items for all size groups. The smallest size group frequently preyed on polychaete and bivalve larvae, along with copepods. As notochord length increased, the numbers of cladocerans and Macrostomida increased relative to those of polychaete and bivalve larvae.

This study was conducted to examine the needs of nutrition education based on analysis of the eating habits and nutrition knowledge among middle school students. The survey was conducted on 536 students (boys=216, girls=320) using a questionnaire. The average number of meals consumed was three (67.5%) and 58.0% of students reported having breakfast. Concerning the nutritional knowledge, students showed the highest score (girls, 0.90${\pm}$0.03 and boys 0.82${\pm}$0.04) for items describing the proper diet plan for obesity. Additionally, nutritional knowledge was found to have a significant effect on dietary habits. Regarding the necessity for nutrition education, high response rates for "For normal growth of students (44.8%)" and "Help to select proper food and choose safe food (24.0%)" were observed. Taken together, these findings indicate that consistent and systematic management is required under the institutional support by the school to improve students' perception regarding nutrition and to develop effective nutrition education.

The feeding habits of Spanish mackerel (Scomberomorus niphonius) were studied based on the examination of stomach contents of 445 specimens collected from January to December 2004, in the Southern Sea of Korea. The size of Spanish mackerel ranged from 26.1 to 105.4 cm in fork length (FL). Spanish mackerel was a piscivorous fish which mainly consumed teleost fishes such as chub mackerel (Scomber japonicus) and anchovy (Engraulis japonicus). Its diet also included small quantities of shrimps, stomatopods, cephalopods, crabs, polychaetes, amphipods, cumaceans and copepods. Smaller individuals (<60 cm FL) consumed small fishes such as Engraulis japonicus and crustaceans. The portion of these prey items decreased with increasing fish size, and this decrease was paralleled with increased consumption of lager fishes such as Scomber japonicus and Cololabis saira. The prey size increased with the increase of fish size.

The objective of this study was to investigate the dietary behavior and preference of vegetable food and to provide preliminary data required for menu promotion for middle school students' proper diet habits for their health. A survey was conducted for one week(2007) in Kyounggi province(Ansan and Seoul). The result was as follows. Three times a day was the highest in the number of eating meals and boiled rice. In the preference of food items, the meat food was more preferred than the vegetable food. In case of vegetable preference, males were higher than females. Many students recognized one dish of vegetable food in their meals. 72.4% of students ate less than provided in the food service system. Also, 7% of students did not eat vegetable foods entirely. They have had 1/2 dish(35.2%) of Kimchi in their meals and only 10.6% of students didn't eat Kimchi at all. The reason that students ate vegetable provided was 'for eating rice'(47%). Also, the reasons that students do not eat vegetable provided were 'bad taste' and 'unfavorite vegetable'. The above results indicated that it was needed to understand the importance of vegetables and education about the nutrients of vegetables.

The effects of a nutritional education program featuring cooking activities on 20 preschool children 6 years of age at a kindergarten in the Daegu suburb area. After applying the nutritional education program for 6 weeks, scores of dietary habits, dietary attitude and problematic dietary behaviors increased significantly from 3.68 to 3.83, 3.52 to 3.9 and 3.59 to 3.89, respectively (p<0.001). Problematic dietary habits, such as not eating a variety of foods, overeating, and having an unbalanced diet, were positively affected while problematic dietary behaviors, such as eating too much sweet food and liking instant foods, also underwent favorable changes. Among dietary attitudes, washing bands and brushing teeth before and after meals were the least changed items (0.15 out of 1). To improve dietary habits and behavior of preschool children, nutrition education programs cooking activities must be applied systematically.

The purpose of this study is to analyze the contents of the questionnaires used in dietary surveys and to evaluate each item in relation to the item construction strategy. Articles of which the contents were related to food, nutrition, diet, dietary behavior, and related areas. Published from 1997 to 1999 were searched fir and a total of 121 questionnaires were collected and analyzed. The questions in the questionnaires were classified into related areas and sub-areas. Among the keywords in the title of the articles, the term 'nutritional status'(or 'dietary intake status') was most frequently used. The terms such as dietary status, obesity, health, food habit, and dietary behavior were also frequency used. Major topics of the items in the questionnaires varied according to the life cycle of the subjects of the study. The topics most frequently asked in each lift cycle were as follows : overeating, snack, and food preference for preschool- and school-aged children ; anthropometry, weight control, and snack for middle and highschool students : meal skipping, smoking, and drinking for college students : disease, smoking, drinking, and exercise for adults : and smoking, drinking, disease and perceived health for the elderly. Inappropriate questions with complicated language, typographic and grammatic errors, unnecessary words, and negative questions were found. Therefore, care should be taken to construct each question so as to avoid possible misinterpretation. Also, a standardized questionnaire be developed for survey researchers.

The egg's interior quality is one of the most important criteria for commercial producers and consumers. Internal quality is complex, including aesthetic factors such as taste, freshness, nutritional and processing values, and the genetic influences upon these upon these factors ranges from none to considerable. The rate of cholesterol synthesis in the hen is very high compared to other animals and humans. Genetic selection, diet drugs and other chemicals can alter cholesterol concentration in the plasma of laying hen, but attempts to manipulate the cholesterol concentration in the egg yolk are generally unsuccessful since the cholesterol can only be changed to a small extent. Factors which may affect the degree of pigmentation of the yolk include the type of xanthophyll and its concentration in the feed, the feed composition, and the health of the hen. Several feed ingredients interact with carotenoid pigment to improve or reduce their deposition rates in yolks. Egg weight is determined by genetics, body size prior to first egg housing density, environmental temperature, lighting program, total feed consumption, calcium, phosphorus, niacin, water, methionine, total sulfur amino acids, energy, linoleic acid, fat and protein levels. Eggs need to be promote levels. Eggs need to be promoted a versatile commodity and new processed egg items need to be developed. Organic eggs are laid by hens which were raised in chemical and drug frdd environments. There are still difficulties in producing these eggs due to the availability of organic poultry feeds and cost of organic grains.

This study was performed to investigate the adequacy of dietary fat and protein intakes among female college students. Daily intakes of energy, fat, protein, major amino acids and other nutrients were measured in 52 female college students. Daily energy intake was 75.8% of the recommended intake. Fat and protein consist 19.2% and 16.7% of the total calorie, respectively. The average protein consumption per day was 105% of the recommended intake. Essential amino acids intakes were more than the recommended amounts which appears in the 6th edition of Recommended Dietary Allowances for Koreans. However, when the intake of each essential amino acid was compared to the recommended amino acid requirement pattern, these subjects did not meet the estimated requirements. There was a highly significant correlation between daily protein intake and lipid intake implying the major sources of protein in the diet were also major sources of fat. Daily intakes of dietary fiber, vitamin C, iron, and phosphorous were above the recommended levels of intake. However, blood hemoglobin concentration was marginal indicating dietary iron consumption is not a good marker for iron status. Also, calcium intake was only 63.5% of the recommended intake. Therefore, these results imply that main problems for these subjects are low energy consumption, low calcium intake, and the quality of protein. However, as opposed to the hypothesis, the main energy sources were not the food items high in saturated fats such as instant foods, which should be emphasized further.

Objectives The purpose of this study was to investigate the relationship between counseling skills and Sasang constitutional medicine(SCM). Methods Reviewing the texts relevant to SCM, comparison between counseling skills and the excerpt from the relating books was conducted in terms of the attitude of the counselor, the observation method, the evaluation of the counselee, the relationship between the counselor and counselee, and the counseling method. Results As the attitude of the counselor, many kinds of attitudes and skills including respecting the counselee and reciprocal belief were needed. The excerpt from "Gyeokchigo" meant that the counselor or a doctor should have the virtue of Truth. To evaluate the patient's problems in SCM and the counseling, diet, digestion, and sleep could be asked, but questions about the emotions such as Joy, Anger, Sorrow and Pleasure should be more carefully modified in a modern way, when applying clinical practices. Empathy as the main principle of the counseling could be attributed to the main idea of Dongmu Lee Jema, in which all the people could be in the same status in a natural way reflecting that they like the virtue and dislike the evil. Recommendations of regimen and directives could be followed according to SCM Conclusions Several items of counseling skills and SCM coincide but some of the modern counseling skills are still needed to apply SCM to make the patients with psychiatric problems treated efficiently.

BACKGROUND/OBJECTIVES: The dietary intake of foods with fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) is known to adversely affect patients with irritable bowel syndrome (IBS). However, the effects of FODMAP have been studied predominantly among Western populations. This study aimed to identify foods high in FODMAP content which form a part of the Korean adult diet and obtain basic data for the preparation of IBS guidelines. SUBJECTS/METHODS: An online survey of 1,000 adults from the general population in the age group of 20 to 40 years was performed. Data from 787 participants (men, 386; women, 401) were analyzed. The general characteristics of the participants, health status, IBS diagnosis using the Rome III diagnostic criteria, semi-quantitative food frequency questionnaire findings, and food items causing symptoms were analyzed. RESULTS: Overall, 169 participants (21.5%) had IBS. The contribution of the FODMAP nutrients in both IBS and healthy groups was as follows: fructan > lactose > excess fructose > sorbitol > mannitol > galacto-oligosaccharides (GOS). The fructan intake was 4.6 ± 2.2 g/day and 4.3 ± 2.5 g/day in the IBS and healthy groups (P = 0.014), respectively. In the IBS group, the ratio of the intake of fructan to the total FODMAP intake was 39.5%, 29.8%, and 5.8% through onions, garlic, and bananas, respectively. CONCLUSIONS: Fructan was the FODMAP nutrient most consumed by Korean adults. Therefore, given the difference in the dietary habits of each country's population, the dietary guidelines for IBS should be country specific.
